FEATURES
Output Voltages Set Internally to ±1% Output Voltage: +5 V (Contact Factory for other voltages) Internal Overload protection Hermetic TO-3 Package Thermally Optimized Package 100% Hi-Rel Tested Compatible with DLA 5962-8777502YA MIL-PRF-38534 Certified facility
Applications
Power Management Local 5 Volts regulator Low noise Power Source PRODUCT OVERVIEW The LVR-123 positive regulators are supplied in a hermetically sealed TO-3 package. All protective features are designed into the circuit, including thermal shutdown and current limiting. This series of regulators can deliver over 3 amps of driving power. The LVR-123 regulators are internally trimmed to provide a nominal voltage accuracy of 1%. The LVR-123 accepts a wide input voltage range of +7.5 to +15 volts and it has a +5 Volt output. Models are available for use in commercial (0 to +70°C), extended (–40 to +110°C), and military or Hi-Rel (–55 to +125°C) operating temperature ranges. The QL model is equivalent to DLA part number 5962-8777502YA, is rated is over the operating temperature of –55 to +125°C, and is subjected to all environmental screening as the 5962-8777502YA model. Every unit is 100% tested for its rated grade and over the specified temperature. The LVR-123 products are built on DATEL’s MIL-PRF-38534 certified production line. They are the best choice for all military, aerospace, ruggedized, and demanding applications where a Hi-Rel and hermetic package is required. RoHS and Non-RoHS compliant models are available for all grades. FUNCTIONAL BLOCK DIAGRAM

With a heat sink, the effective thermal resistance can only approach the value of 2°C/Watt, depending on the efficiency of the heat sink.
